I would want the CLS as it looks great and is a real head turner.
+side is the cls looks great and is performance oriented
- MB classic reliability which is poor along with there service department
is only a 4 seater with very low headroom for rear seat entry. If you carry anyone over the age of 70 it may be a problem.
GS430 is fast and looks great also but not as nice as the CLS right now.
Since you are going from a Jag the MB will seem pretty reliable , unless you have the Lexus you won;t know the reliability experience.
For the price the GS430 is better but if i had time and cash to waste on service i would get the CLS.
That is just plain stupid to say that any upgrade will provide no yields.
On any car over 5 years it is a good idea to look at the grounds. You will never gain any power from the kits but will reclaim lost horsepower from degraded wires.
Now do a search for the rest of the info already posted in detail.
The wheel is not a direct replacement .
You would need an airbag which would not wire to the newer gen 2 SRS systems.
You can get an oem wood wheel and transplant the wood onto the existing leather wheel.$200 plus lots of labour to colour match the wood grain and sand.
You can send it to American stitches. $400-500
Buy an aftermarket Nardi or MOMO wood wheel if it has no airbag. $500
Get a clip on cover that seem to match pretty good $50
The oem wheels are in the 1700 - 2500 range.
The tilt and retract would still work fine as it has nothing to do with those systems.
The different hue's of blue are from a sharp angle/cutoff on the edges of the projectors causing a purple colour but it is the same bulbs as everyone else.
A power door lock kit is plug and play all wiring is harnessed ,you just add power and ground no other wiring to it.
It uses steel rods held onto the stock lock rods ,so the solenoids move the rods in the same direction.
1.5 hours max to do all 4 doors
Your mechanically inclinded ,so pick up a 4 door power door lock kit for $50 and install it yourself for free.
The hardest part is fishing the wire through the loom for the doors. But with no power options it should have lots of space.
By adding new fluid you may have loosened the blockage with its fresh cleaners. The build up has returned and needs to be completely flushed ,i would add the inline filter for a piece of mind as well.
For the bumper to peel like that it had to have not been repainted properly.
Factory finishes are baked and if they even try to peel it is going to come off with the urethane under it as well.
