The pics above are at least 3 different cars, maybe 4. First pic has flat topped headrests, engine shot is a blue car, 3rd shot with beautiful paint has the curved headrests, and 4th shot of blue interior hardly ever is in a beige colored MB.
Look for one as clean as pic 3 and be happy. A non-turbo has less power of course, but can have less headaches too. {leaky turbo drain, clogged boost line, turbo in the way, etc....}
I enjoyed my non-turbo wagon, and I would always pic the cleaner, more solid car, turbo or not.
Heck, I love driving my 240's the most, so a NA 5cyl would seem fast......

**the high altitude warning has much merit, though**
