A LOT of info on here regarding VCU, 3 Amigo's, MAF etc etc.
I bought an 05 auto commercial to do a bit of towing and generally to go fishing in. I've spent about £1500 on it. Some of that unlucky. Some getting it to better than original standard (synergy 2 kit).
I drive all sorts of other cars, vans, trucks - but for some queer reason, I quite like driving this one.
Welcome to the forum, some harsh sounding trattor driving types on here, but generally you will get a LOT of advice (mixed in with a fair bit of gay lander abuse).
Good luck - don't rush in and buy a pup.
