Like I said, if I was comfortable in the Honda, I would have bought one.
I already had a Honda Dealer ready to sell it to me at MSRP the first week they came out. Unfortunately, he didn’t have one in stock.
I went to another Dealer and sat in the only one they had and I was disappointed I wasn’t 5’8”, 150 lbs.
LOL
Great car, has everything you need and nothing you don’t. I call the Miata an “Old Lady Car” because my Mom bought one the first year it came out and still has it at the age of 78. ;)
Those are nice, but they get scary money for them.
Vacuum .. is created by lifting the gas pedal as the engine starts to suck.
It was originally used as free energy to assist in shifting an automatic transmission.
Why a “vacuum pump” is needed for braking is beyond me. Power brakes as well as power steering came from “positive” energy.

Yes you get vacuum when you lift or operate at part throttle... when you are at a “track day” event you may not be off the throttle long enough to build vacuum especially with a supercharged engine. If you are “two pedaling” the car (never letting off the gas and just using the brakes to settle the chassis entering a corner) you will not have vacuum.. or to put it into a “street” scenario ,, you’re charging up a mountain road where you never let off the gas and are in a positive boost scenario...
Engine vacuum was used as a trigger to shift automatic transmissions (the vacuum modulator) but the transmissions all worked off of HYDRAULIC pressure generated internally, engine vacuum was just an indicator of throttle position and engine load. The vacuum modulator operated a hydraulic valve back in the analog control days and altered preset shift points (determined by pressure) to match engine load ,, now we use sensors for RPM , throttle position and “map” sensors and such to operate electrical actuators within the transmissions.
Vacuum is vacuum no matter if it is a engine pumping against a partially closed throttle or it is a vane type air pump run off of a cam chain..
The new NSX is going to be a hybrid (v6+3 electrics) and about $150k...
They’re also talking about a “new” S2000 in a mid-engine configuration with a turbo and ~300 HP.
Hard to improve on the mine IMO, a non-turboin-line 2.2 liter 4 cylinder with 244 HP and a redline at 8K.
As a peon, I can only marvel at what it must cost to insure these mega $$ high perf vehicles.
I saw that the first Hellcat Dodge sold was totalled in less than an hour and was sold for 20 grand over sticker, of course that isn’t part of the coverage.
My S2000 costs the same as my 2006 Nissan Frontier 4x4 in terms of insurance.
Absolutely. The diesel has no combustion chamber other than the thickness of the head gasket. IOW...no room for both the piston and an open valve.
Better check when you last got a timing belt.
3 year old used car, she had it for a year, You pay your money and take your chances. She should have bought a Toyota, she would still be driving and happy.
No surprise there, it has to be at least 6 years old, right?
The last ones were built in 2009.
It’s a 2005. What’s funny is that they’re going up in price recently... I’ve seen similar ones with more mileage that are getting $4-5K more than I paid a while back.
Also, finding a used one that hasn’t been modified or thrashed is getting harder. Mine was one owner, and the only thing that wasn’t stock was a set of new Michelins. That translates to “old guy owner” cause a kid would have spent that money on rims or such.
"Boost" engines don't have usable vacuum.

It’s been some time since I had a vehicle that preformed the way I wanted running “full throttle”.
Two peddling is a given since you need to maintain RPMS while setting or shifting weight for cornering.
I’ve always used my left foot for braking and have no idea why kids are taught “not” to use their left foot.
There have been soo many cases where people thought they where stomping on the “Brake” when in fact they where on the gas. Sudden acceleration syndrome, it nearly bankrupted Audi and Toyota more recently.
Sadly, most people don’t understand “how” an automatic transmission works. There is that little thing called “Stall speed”.
At the end of the day I wish that automakers would move away from the complexity they have engineered into everything and get back to a few basics. It seems to me that they do this as to keep control over both maintenance and repair.

Honest question that you “may” have just answered.
I’m pretty certain that it’s been proven that a “human” driver can not shift as fast as an automatic transmission.
IIRC, it was Nigel Mansel, driving for Ferrari at the time that destroyed the field with an automatic transmission.
Your statement makes sense if applied to “Drag racing”.

No, it applies to any supercharged or turbocharged engines. If they have positive manifold pressure (more air then the engine is naturally trying to pull in) then they can't have negative manifold pressure (vacuum).
IOW: Boost pressure is the opposite of vacuum.
It has nothing to do with transmissions.
So, why do drag racers still shift manually ?
I understand positive manifold pressure as well as the source of vacuum.
Aren’t drag cars supercharged ?
Forced air ?
Turbo charged is slightly different as it works more on the back end vs. the front end like superchargers.
Turbo works best at high rpms while a supercharger is always on.
I don’t think there are many “Turbos” on the drag racing circuit.
Manual transmissions are sometimes used in racing just to add a measure of driver skill (NASCAR, for example), or, in many racing classes, to help keep costs down for competitors.
10k is pricey for a lawn mower engine? Lol. I guess so when you can buy a 2011 Hyundai Sonata with 30k miles on it for 10k. Which is exctly what I paid.
