Think he's keen to spend your money. Sit tight, there's no such thing as a bargain, loads of driving schools use them for multiples of your mileage same age. The i30 seems to be the 'New Corolla'.

This is always a difficult one. What Jog-on and Bobbin say makes perfect sense, but the other side of the argument is that if you change it now when you can get a reasonable price for it, then the 'cost to change' is manageable.

You either change it now or run it on till it wears out - say at 7 to 10 years old, depending how well you look after it. As you've realised, now (3 years old) is the decision-point.

Finance is of course not the only factor: if you like having a new car and want reliability and no unexpected bills, you'll want to change. Personally that's what I'd do, and if you do only 8,000 miles a year you should think about a petrol engine, which should be cheaper to buy new or nearly-new.

General rule : Once the MoT is due, let someone else deal with the hassle.

Firstly, you receive no benefit from diesel at 8K miles per annum. If you do change go for petrol. I have covered both scenarios over the past 40 years or so. I have changed at regular intervals and aslo kept some until worn out. Keeping them until worn out makes better financial sense. Provided you look after them well you get cheap motoring over say 6 to 10 years. I ran a Honda Accord for 12 years to 157K miles. Great motor. I am now into year 6 with my Skoda at 128K and going like a dream. Should last another few years yet. However I do about 23K per annum, mostly motorway, low revs etc so engine is well used and clean. Clutch and brakes only minimal use and over 50mpg from diesel. My advice, keep the car until it drops then divide your outlay by the time and you will be pleasantly surprised at how cheap your motoring has been. Good luck,Concrete

I can see little advantage in contemplating this, and even less good math.

You've nicely run-in the car with 25K, endured the steepest & most costly part of the depreciation curve (and I presume the you're 1st owner), & have a known & reliable quantity.

Your 2.5K might buy you a 1yr old car - but who sells a Hyundai at 1 year? You're buying unknown provenance. For your £2.5K you get 2 years extra warranty & 2nd owner V5 7 the privilege of 'enjoying' again the steep depreciation part of the curve.

The math: I doubt your Hyundai will depreciate 2.5K in the 'extra year' as you say, if it's only lost 2.5K from year 2 & 3 - after all, you'll still have 1 year warranty left at year 4 & minimal mileage.

MOT worries? Really, nothing at all should deteriorate until years 6-7 (maybe then,only an exhaust , or sidelight etc), the rest are consumables, tyres, brakes etc. (I imagine you've even got a newish 2nd set of tyres @ 25K?)

I could see the point if you were changing model (in the i30 range), or buying a really 'knock-down' priced petrol version (in view of your mileage) or think there might be problem ahead etc, but other than that, no.
