Given you plan to keep the car for 4-5 years, and given what you plan to do with it, i would't be unduly concerned about the resale value. That sort of mileage is going to make a big dent in the value of any car. If you are starting with something cheap, the depreciation is going to be a bigger percentage of its purchase price, but i doubt the actual amount you lose would be much more.

What i'd be most concerned about (after relaibility) would be comfort and refinement, because of the time spent in the car. In terms of comfort (looking at owners reviews), Suzuki seem to do OK, but in terms of refinement, not so much. Suzuki's tend to weigh less than the competition like for like (Avant, the 1.0 manual SX4 S Cross only weighs 1160kg, which is about the same as a Fiesta), and one of the area's for this would be sound insulation. Reading reviews for Suzuki's, they are generally quite noisy at main road speed. So i'd be looking to give the car a good long test drive, taking in a section where you can get it up to 70mph+ to see how you find it.

By contrast, the 9th generation Civic SLO mentions, is one of the most comfortable and refined cars in its class.

You should be looking for the best car for your needs, not the newest one. And that, IMO, does not need to cost anywhere near £11k. I could find an old Toyota Avensis for under £3k which i'd be quite happy to spend that amount of time behind the wheel, and be confident in its reliability.

Just to throw the proverbial grenade in to the mix...

Rules for the car (stipulated by work) is:

Under 10 years old.

Under 110k miles.

Unfortunately a 5 year old car with 50k on the clock would be ideal privately, it would not be suitable for work as after 2-3 years it would be outside of the requirements mileage wise.

I knew a high mileage driver wanted the very best for every £ but wanted a newish & reliable car..

He bought 2/3 year old car with 15K-20K - kept it 2 years or with 60K ish miles

Still very sell able at a good price.

Then started the ball rolling again with a 15-20K car

I looked at the SX4 myself. Its larger than the Vitara. I wanted the 1.4t but at the time they were like hens teeth. Buyers buy them to keep. Make of that what you will. I settled for a Vitara bit smaller but I got the1.4t engine. I also have a Swift with the1.0t engine and it's a decent engine. I suggest you do an extended test drive. .
