When I bought my V5 many moons ago I had the choice between a 1.8t and the v5, I bought the v5 purely for the soundtrack !!!!
I, well my wife could get 35mpg out of it on a run on the mway.
changed a few things on mine to help it ……
changed the rear engine mount for a harder one to stop the slop in the gear change.
fitted a miltek exhaust which made the engine note even better.
had it remapped and then was running around 190bhp and gave even better fuel consumption.
If i could find one now with low enough miles on i would have one as a second car !!
also had 5 coil packs and the cooling fans done on mine too.
make sure you get one with the sports suspension to as its a boat without it !!
