The motor is a 3800 Series III L32 which has the upgraded GenV supercharger which is a plus if you want a little extra power. However you will have to burn premium gas in that car. The motor itself should be as good as any other 3800 with those many miles. A lot of people on here have way over 200,000 miles on 3800's. If I was looking for a bad weather car I'd want to burn regular gas but that's just me.
