VASILE

Vauxhall Astravan • Alternator replacement

8th March 2018
“Mark checked out a used Mercedes Benz that I wanted to buy which on paper seemed to be very impressive. The comprehensive report he gave me soon after he had inspected the car, was detailed and thorough. The diagnostic test was able to reveal a problem that could potentially have costed over £1000 to repair. As I am a complete novice to the technicalities of car engines, he was able to give me an idea of the nature of the potential problem as well as recommend further research through looking at car forums online. By this, I was able to make an informed decision that saved me some hard earned money!“
