Probably easier and better to just buy a new GR86. I have a 03 5MT E46 330Ci that is just a $5,000 3,000 mile a year fun car and that was a bitch to find. I probably have already too much money into it. I’ve been looking at the spec E46 racing series and to buy the modifications to make it a racecar costs ~25k. Not including installing parts, welding in the cage and chassis support, and gutting the interior. At VIRingia International Raceway the SpecE46 class laps about the same pace as a GR86 Cup Car. (The SpecE46 class is faster than all the E36 spec classes) Putting $3,000 suspension on a 30 year old car and shit like that is just plain dumb to a layman. I’d buy a new Toyota GR86.
That 2011 Audi S5 Coupe with the V8 is an affordable dream car for me. Saw it every day at the boardwalk
