'88 300CE buying advice

[Kyle Blackmore]

I'm on the hunt again.....found a nice coupe that I hope only needs some TLC. These are some of the things I found:

• Water in driver footwell
• A/C needs pressure switch, seller will fix
• Poor quality paint touch-ups
• Rear window is foggy in lower corner(delaminating?)

I haven't driven the car yet but just had a quick look at it this morning and it seems to be very nice. Though it is
underpriced by about $3000 which has me wondering why? Do these cars have similar water problems as 123's and is there any other common areas or items that I should take a special look at after I test drive it???
Thanks in advance,
Kyle
