Well when it was Wadham something trade prices were easy for the year or so we had the Carlton before FIL retirement - ask the FIL. Managed to blag for about 2 years after but staff change and people get forgotten.
The last three garages my dad worked at were all pretty good, Peugeot for quite a few years until closure after buying Talbot and merging dealer network, BMW until closed by a tosspot at Lloyds while the account manager was on holiday*, then Subaru & Skoda until retirement.
*Stealer in another town was moaning about losing business to the one my dad worked at, since the manager knew someone at BWM UK they managed to get the franchise pulled, while legal battles were going on a bank w**ker (or or an) who looked after accounts during their managers holiday pulled the plug.
The stealer who cost my dad his job were rubbish at servicing, oh and I found out the managers son was cheating on his girlfriend or fiance!!
My dad went straight between Peugeot and BMW but took a while to go to the garage down the road.
Anyway I do tend to worry about garage servicing, and get annoyed at not being able to blag cheap prices!
