Recently purchased a car with similar requirements to yours.
We had a Mazda 3, which mechanically was sound, but underbody corrosion and a potentially costly air bag warning light meant we decided to get rid.
We’ve just picked up a Focus, so probably the same as your current vehicle.
For your budget I reckon you could pick up a Honda Civic, with the clever seats for easy bike loading duties. Owing to reported problems with the 2.2ctdi you may be better off with the 1.8 VTEC, esp with your low mileage.
