Servicing & repairs Yorkshire

[JapanRed]

I've had my first ever Porsche, a 2008 gen 1 997 911 since February. Since then it's developed a bit of a hesitation at 2100 revs which I want to get diagnosed.

Can anyone suggest where to get this done? I assume Porsche dealerships will be much more expensive than Indys?
Which are the best indys within an hour of Leeds?

I'm looking to keep this car for a decent length of time so finding a garage that I can trust, and that's not likely to rip me off, is paramount.

Thanks guys. Prior to seeing your responses I was going to go with Porschetek but seems like Revolution wins the vote.
Both are same price for fixed servicing so I'll go purely with the highest vote and will ring them in the morning.

Many thanks,
Rob
