What's your choice:

I want opinions if i have made a mistake with my choice:

i had tried the driver's seat of a 94 C class (cost: $16K) and it feels like seating in a japanese car which i previously owned. although i have not drive it, i think its as bumpy as jap cars.

with my 1992 e320 4 drs (costing $16K), i have spent around $1800-2000 to repair its drivability problems, etc.

replaced the ff

alternator
distributor cap
ignition coil
plug wires
several spark plug changes
rewiring the engine harness
modify my fuel pump relay wiring to match it with the fuel relay for 4 zyl since i cant source the MAS relay
fuel filter
timing cover seal
valve cover gasket
idle control valve
fuel pressure regulator
tie rod assembly
front shock mounts
