Ton, I have bought and sold cars nearly all my life...... call it a 'Lad's thing' and for me there are three ways to go.
Buy new and keep it till it falls off the axles.
Buy a banger for a ton and run it into the ground. Scrap it for £40, then get another.
Go secondhand for the best you can get for a reasonable price, then spend a few quid bringing it up to scratch, but only if it is worth it.
Sometimes you and the seller get lucky, as I did buying Agger's Nissan NOTE. Hopefully we are both happy, I know I am.
What you not do, unless you are rich, is buy new car and sell to get the next new number plate - depreciation on the first year costs a fortune.
Don't buy a mid-life car for a premium price. When one thing starts to go so do a lot more things, so you end up doing repair after repair.
However, If you do buy a mid-life car that is sound and for a reasonable price, and you sort the minor problems out - brake pads, oil and air filters, alternator, then you should be OK.
Ton, you look to have bought a runner, not brill and not bad, and it should last a few years, but don't spend too much on it. TBH I would be looking at a lesser marque a few years younger and doing a swap. Sorry, but that's me.
