I'm booked in for a Works upgrade on my 04
MCS this Friday. JCG gave me 250 quid off the suspension upgrade which I am having done at the same time. Not quite a bargain at 650 pounds but better than the advertised 900 GBP. Total price is 4657 inc VAT (that includes a pair of front spots also). Yes I know a could get a BBR Phase 2 for that but insurance ease, re-sale and warranty concerns pushed me to
JCW.
The discount really made the difference as I was sitting on the fence as to whether a suspension upgrade was worthwhile at this moment in time. I'm not sure if many others would entertain a simultaneous JCW210 and suspension upgrade but if you are that way inclined, it might be worth asking for a similar discount.
Off thread: As an aside my insurance went down 140 GBP

; how bizarre is that. Try First Alternative!
Cheers
