Last year I bought a 2013 BMW M3 Convertible, the last year of the V8, 44k miles.
I’m treating it well, hopefully it returns the favor!
Hopefully the M3 has better calipers, the standard E90 has crappy ones that go at about 8-10 years or 80,000 miles. Hopefully the rack doesn't go, that's a 4k plus job. Bilsteins may leak at 100k......not to mention other electronics.
