I have a 99 with almost exactly the same mileage.
I would differ on the serviceablity. You don't mention your resources, but I realized early on that most service is far more easily accomplished with a lift for these cars. I really don't find it hard to work on it even though I no longer have the lift, but a quick jack (which is just better than jacks and stands.) Being a mid-engine vehicle, it is never going to be as accessible as a conventional layout.
Mine hasn't had a lot of engine lights. The one time it did was when the coolant tank, tanked. That is the only time I've had a failure. German plastics are a common problem in my BMWs as well.
This one is a very comfortable for trips, and yet I took it on-track a few months ago where it did great. It's not fast, but the fun factor is uncanny for the age and power.
That oil issue you found is due to the Driven using ingredients lacking in most oils for reasons of fuel economy and some questionable political engineering. Check with the Oil Guy for more detailed explanation of why you want something better for your engine.
Glad you like yours!
