I'd be very surprised if the wheels of W202 could fit a W203 (offset for one) since the front suspensions are so different.

It really is a beautiful car and Ronal or BBS for example may make a good looking wheel if you go 16 or 17 inch diameter. I like the AMG style split spoke even the traditional BBS style on that car, all about price.

Here are some tips for checking out a W203

a) look in the drivers foot-well up under the dash and compare to other cars, your looking to make sure there are no dropped/exposed harnesses, there should be a black plastic piece covering the wiring above.

b) go through the steering wheel (left )buttons to view the dash display and make sure you get a - O MALFUNCTIONS - reading.

c) feel carpeting for moisture under the floor mats, check rubber on brake, gas pedal to notice if waffle imprint is worn or matches wear for the mileage

d) make sure all buttons work, express windows, sunroof, all fog light (rear), EC REST red light glistens on the HVAC unit when pressed on.

e) check battery in engine compartment passenger side firewall under HVAC filter check condition, make, cleanliness.

f) trunk floor for spare tire condition, cleanliness, scratches, jack.

g) wheel-well plastic cladding for flushness and rubber flexible wind deflectors at sill level in front of all four wheels.

h) have a dealer inspect car for CRASH DAMAGE, and all suspension linkage etc.
