Well I had it done yesterday and extremely happy with it.
Would certainly recomend Pete and Autotech.
It came in at £596.95 which was slightly higher than the original quote but Pete did tell me the quote was from memory when originally enquiring.
If you intend getting any work done at Autotech I would suggest getting the Bus or Cab (£8.50) to Telford Shopping Centre as you'll need something to do whilst your work is being carried out. All the usual shopping centre shops and a big Wetherspoons for a cheap lunch and a pint. Pete gave me a lift there but I declined his offer of a pickup when my car was ready. I hadn't realised that it's about 5 miles away and and about a 30-40 min round trip. Nice of him to offer but must be a PITA for him.
Here's a piccy of the f****d motor. Apparently the well where it sits had a load of sediment/sludge in it. I'm guessing then that the regular cleaning of the drain is only boring a hole through the sludge rather than actually cleaning the well out.
Was also told that this wasn't the first replacement motor the car's had so this new one is probably the 3rd.
Overall a 10/10 and Autotech are highly recommended.
