These cars are 20 years old and require constant maintenance to keep as a daily driver. Mine is my DD and has 250K+ on the odo. But you need to be certain you will be working on minor crap constantly.
TSI or not does not matter. 87 - 89 are the best years with 88 - 89 having the stronger axles etc to hold up to upgrades. We have guys running reliable daily drivers with 300+hp and steady 13's and lower.
I've had 13 of these cars over the years and am a bit biased when it comes to Moparbishi's.
