Found this on PistonHeads today:
"Right the range has been reduced by about 5% across the board; the C350 has the biggest reduction at 6.9% to compensate for the cease of production of the C280. This means the list prices for the diesel Sports are:
* C220cdi Sport (170 bhp)- £27,758.40
* C250cdi Sport (204 hbp)- £28,813.40
* C350cdi Sport (224 bhp)- £32,620.00
They reduced the OTR prices on the 8th May, so the above prices shold now be whats being offered at retailers.
IMO the best option is still the current finance deal on the 220cdi, this engine isn't changing in power, just gaining the 'blueefficieny' rating, so you won't really be gaining anything by hanging on. I'm fairly certain the deals won't continue in Q3 because stock levels are so low, so now is a pretty good time to get out and buy one.
Still no news on the C320cdi being added to the finance deal unfortunately."
