DDB Mechanical in Pendlebury Road Cardiff.
Tell Dennis Aaron Treay sent you. He knows his way round my MR2's. He took care of my recent engine build organising the forged bottom end etc.
I'm picky as I've found Newcastle is full of guys who know exactly 7/10's of sweet FA. I've had so much work carried out around Newcastle and have found myself rarely happy. One mechanic actually blew up a brand new engine in my 65 falcon. Another mechanic I took my Corvette to cracked my front bumper but tried to hide it from me thinking I wouldn't notice. the freight on the front bumper is more bloody expensive than the front bumper!.
Anywho. Dennis has experience working on my last 2 MR2's. He bends over backward and if he identifies issues I have found, he tends to ring me and get permission to get them sorted (like my alternater had issues. He rang me and ended up getting a sparky to come out bring a new unit which Dennis sourced and fit it up, I still picked my car up on the original agreed time)
His prices are nice too. I think what makes him good is his love of left field cars. if you go there check out his turbo V8 BMW Z3!.
Cheers
Treay
