Easily, last car was a Volvo v70 bought for £350, from e bay, unseen. Did a years happy motoring, covering 12k miles, coming up to mot time, thought it would cost a few quid, so sold it for scrap for £200.
Found myself a little, fabia estate, again with 12 months not, high mileage, but impressive condition an service history. Covered nearly 4k miles in it, no bother, and it returns 47ish mpg. All for the staggering sum of £450. It can be done, if you know where to look.
