Hi,

I've been reading quite a few posts on advice about diesel vs petrol with a lot of people recommending a petrol for this sort of mileage which confuses me slightly. I do get how new petrol cars these days can do almost equivalent mpg but I didn't see much talk about depreciation. Surely petrol cars depreciate more with higher mileage than diesel?

My work commute is about to go up to 60 miles a day, mainly a fast dual carriage way for about 50 miles of it. On top of that I do another 4-500 miles a month socially which will equate to around 1700 miles a month, around 20.5k miles a year.
I basically need a hatchback (for the dog), 5 door, ideally something which is fairly quick - my guideline on Autotrader is something which does 0-60 in under 8 secs)

I currently have a petrol 2015 Kia Ceed GT (27k miles) which while I love is awful on mpg and car tax (£220 a year) Small loan of £2600 outstanding - £141 a month)
I did my current commute of 30 miles a day for a week (12 miles of this motorway) last week driving like a saint which resulted in an mpg of about 33.5 mpg. This thing is going to cost me at least an extra £100 a month, £1200 extra on petrol alone a year. I did consider keeping it but in another 4 years this car would have done over 100k and would probably probably worthless. The only thing in its favor is the remaining 4 year warranty (which also expires at 100k) Paying off the loan doesn't make it any cheaper than the cars below.

My sums say that with a car doing over 50 mpg (I've been using honest johns real mpg rather than manufacturer figures) and £20-30 tax I will be saving about £130 a month even with a small loan.

My budget is £12,500 (£3k of this is a low interest loan - £110 a month)

I was considering a petrol Seat Leon FR 1.4 EcoTsi for mpg and some poke but again the depreciation of a petrol car is putting me off.

Diesel wise considering the Seat Leon FR TDi 184 and a Golf GTD circa 20-40k on the clock.

Part of wonders whether buying a cheaper (£5-8k) diesel with low mileage might be a better option but mpg on older cars not as great and tax more expensive. Plus worried about any oncoming city charging in Euro 5 and older (I live near Brighton and drive there fairly regulary) Euro 6 seems to be the new best norm.

Cheers for reading a rather long post! Any help or advice appreciated!

Here's the thing your Kia will be pretty loaded spec wise as well as being a decent steer & I'm guessing you'll want the same again, here's the thing if you go & buy a diesel it'll be still losing money with all the miles you put on it.

Also the GT's actually hold their money quite well & aren't everywhere (like the Focus/Golf etc) so will probably find a buyer more quickly.

I'd keep it the reality is you won't have to spend a penny on it bar services & fuel because of the warranty, now were you in the position of needing a new car then yes a diesel would make perfect sense, but in your case I'd live with it.

If you decide to go for a new car then the Kia C'eed 4Tech fits the bill with 4-5 years worth of warranty left it's a no brainer:

Thanks for the advice. Unfortunately I can't afford to pay an extra £1200 a year on the Ceed GT in petrol and my sums suggest I can reduce my monthly outgoings by getting a more fuel efficient car that can do at least 50+ mpg. I got a pretty good deal on the GT when I bought it last year and it looks like I'm not going to lose very much at all by selling it. Its the non-Tech one which means slightly less in value.
Its quite well spec'd its not got sat nav, climate control, heated seats\mirrors.

The Kia Ceed Diesel GT-line look quite appealing but I don't think their performance isn't quite enough to scratch my itch. Remapping risk any engine warranty claims. I'm going to sort a test drive on one of them anyway.

I think I want to have my cake and eat it! A quick car with good real life mpg which could hold its value?
