Help & Advice please.

I have just collected (on Saturday) my new - well new to me at any rate - Impreza 2000 Turbo 5 Dr Wagon MY99 on a V plate, first Reg. Feb.'00. I luuuuv it - who said grin factor - your not kidding:-)

However she (the car that is) is now due for her 15K service & anti-corrosion warranty check. My local dealership is Lancasters in Sevenoaks, Kent. Can anyone please let me know if they have had experiances with this firm,ie: are they any good???
