Long established local garage. They have offers for money off their car wash when you buy fuel(usually £20 worth), and they have more bits and bobs for cars than most other garages/service stations(window wipers, polish, oil, etc). They also carry out a range of repairs and MOT servicing. The convenience store is a bit more expensive for most items(as you’d expect), but it’s a good garage for the troubled motorist as it carries out some repair work, whereas most other service stations don’t(maybe that’s why you’d class some as service stations, and this as a garage).
