I enquired about a Kia and was quoted £269 for 3 services. They also offered 7 years free MOT and 7 year warranty.
That is if we bought a new car. They dont seem as forthcoming with the offers on used models.
I have heard that KIA's are not as useless as they once was. Any model post 2010 get fairly good reviews. They are not a performance range nor are they particularly pretty to look at, but, they dont claim to be. For efficiency, cheap running costs they are a good bet
