Just wanted to clarify the major problems with the 4200:
Subframe corrosion £?
Clutch and F1 pumps £?
Suspension and wishbones £?
Heater matrix £?
Sticky interior buttons £?
Cat failure £?
Assuming these are all inevitable problems, what's the average milage replacement on these issues? I know it depends on how one drives etc, but if all these problems are defective there must be an average life span?
Also I realise to eliminate most of these problems a Transport or facelift is the way to go...
Subframe corrosion £? - New subframe is around £850 IIRC plus labour which will be 6-10hrs at a guess... but you will be very unlucky... mine has some surface rust on the lower portion of the subframe where it bolts onto the chasis, i have had it fully inspected by my specialist and have been advised to scrub the rust off, treat paint and protect because it is overall in a good state (job for the spring) I do not want to be controversial but I have noticed it is mainly the post 2005 GS and 4200's that get written off subframes on the MOT, it might be that these have been used year round more so than the older cars. Anyway my rear sub frame will be dropped out soon to fit a formula dynamics uprated anti roll bar so you can find reasons to repair/restore/protect/improve depending on what your goals are.
Clutch and F1 pumps £? - Manual cars can have their clutches relined by a specialist with no problems, this costs around £250-300 i believe. Cambio Corsa can ruin the clutch tangs because of the way the actuator slams the clutch closed when the car is being driven aggressively... so a relined clutch risks tang failure quickly on a CC, often the tangs fail before the clutch totally wears out on cambiocorsas. Back to the point, a new clutch is circa £1000-1200 flywheel is £300ish thrust bearing £450 spigot bearing £100. With Cambio Corsas you also need to worry about F1 pump, F1 pump relay, actuators blah blah. Believe it or not the CC F1 gearbox is actually less troublesome than the equivilent BMW SMG gear box but my wallet and I much prefer a "manual manual"
Suspension and wishbones £? - Euro Spares do pattern wishbones for the rear £650 IIRC, from the dealer they are closer to £1000. Skyhook shocks are £1000/each for new ones (rare that they fail but occasionally can spring a leak)... Springs are £60/each... track rods/drop links etc. £60-100
Heater matrix £? - Part is less than £100 but around 10-12hrs labour... I paid £1000ish with AV Engineering along with some other bids that needed doing they did a great job.
Sticky interior buttons £ - You can send them off to Lorenz/Larry on Maserati Life (he has an account on here too) cannot remember the exact figure but I am pretty sure it was around £650 for the entire lot of buttons (dont quote me of I am out on that!) he tends to keep a rolling stock so upon receipt of your old buttons he will dispatch the new ones straight away. With the soft plastic on the vents I just scrubbed off the sticky using solvents and left it as hard plastic it does not look bad at all.
Cat failure £? - If you get a face lift car with US spec cats then cat failure is unlikely. The Euro Spec ceramic cats have a tendency to fail unless if the car has been driven by a saint for all of its life (i think it has something to do with how hot they get and the number of intense heat cycles that eventually degrades the ceramic). If you go Larini at full price its around £1450 inc VAT, they often come around used £750ish. You can go down the custom route for about £950 but you need a find a good fabricator not some oaf with a lift tube bender and a MIG welder.
Leaking cam covers - Parts are about £80ish and labour 6 hours both sides... It is very DIYable but it took me 12 hours lol.
