Overall

This car just flat out rips. It surprises on the street, on the track, and at car meets when the hood is opened. P car guys hate this car at the track and can't figure out why an old BMW sedan is still attacking their mirrors on the straights. Everything has been painstakingly sorted with the goal of being able to use as a street car that can be driven and to / from track events.... which is exactly what I did for the last 7 years. It's been dead reliable and has never left me stranded, and that includes 11 hour round trips to Watkins Glen and back.

The suspension feels great, J stock fresh and is surprisingly forgiving on the street while keeping the car planted on the track. The engine.... the engine.... not sure what to say, other than holy hell!!!! At WOT, it sounds truly evil. Brakes stand up well to track abuse with stock E30 M3 hardware and custom cooling hoses / backing plates and although they're not what I would call "P car" good, they're miles better than the 4 lug "BBK" garbage I tried.

Cosmetically, this is NOT a track beater. It was washed, waxed and given the same amount of love I lavish on my other street cars. That said, if you are looking for a concourse show car, this is not it. The driver's rear door has a small amount of rust on the bottom edge as does the rear valence under the bumper beneath the battery tray (typical E30 spot). The rockers were still decent but I had them professionally replaced anyway with new BMW ones. Overall, the paint shines well and looks very, very presentable. The interior is also NOT your typical stripped, track day special. It was left mostly intact with the exception of the rear upper seat and retains stock 3 point safety belts for that quick trip to the grocery store. Working AC blows cold and is a huge asset on a hot summer day after a day at the track.

I have STACKS of invoices and receipts from my ownership as well as the PO going back to the original owner. Most of the work was performed by Guten Parts.

I take ridiculously good care of my cars. I am OCD about maintenance, getting the car up to operating temperature, and avoiding short trips (less than 5 miles), especially in colder weather.

There’s probably a lot more I’m missing. I have well over $40K into this. I need to sell to fund my racing dreams. This is probably the best set-up E30 for both track and street driving. I’ve driven to / from DE’s for the last 7 years and never had an issue. Very well sorted car that benefited from years of tuning and set-up.
