Tim and Nathan at Central Garage, Four Lanes (01209 314699) have worked on my current 100 and on my previous Colorado & Surfs. Not Toyota specialists but good lads who have always been super helpful and reliable over the years for me. Very reasonable pricing too.
They don’t tend to deal with diesel injector removal though and they will recommend you towards Helston Diesels (in that little industrial park opposite Lidl at Helston) if you need injectors done. I’ve used Helston Diesels too and found them to be good.
Cheers,
Nick
