Thank you all for your various inputs. looks like we are on the right track. The ix20/Venga and Auris will be added to the shortlist. She did have an Aygo at one time, but it was not really up to the infrequent but long distance journies she made. As with one of the comments I wonder if it is really with the hassle of getting the Yaris through the MOT and then selling as an old banger to a knuckle dragging tyrekicker.

Whilst my daughter has a good range of useful skills that I encourage her to practice I doubt she will be doing any major repairs any time soon, but can certainly draw on the skills of others as and when required.

We definitely want to avoid another "car crisis", having recently experienced one with her elder sister's unreliable car. A planned swap process starting with an MOT for the Yaris well in advance of expiry and identifying of a suitable replacement is now under way to conclude within the next month or so.

After a very good experience with the current one I think I'd seriously consider just getting another Yaris!

Thanks again all for the further input. Another Yaris is certainly on the cards, as a family we have had four over the years and all were good. However a good one needs some finding. There were none on the HJ used vehicle finder on this site within thirty miles of our postcode when I looked. Autotrader showed 28 having removed the autos and/or diesel models. The youngest in the price bracket up to £7.5k was 2016, and of course some very leggy ones. I agree, there is nothing wrong with that providing there is a good service history.

Looking at the selection available I checked the MOT history of a number of high milers. There were obvious signs of neglect with some, mechanical faults particularly suspension components or, a problem with the current vehicle, corrosion. The advisories were very informative. Several were advertised as full service history, as was one I drove 30 miles to see recently - the service book showed two stamps and the third service was essentially somebody writing the date in. No invoices were available. Winnowing down the shortlist of 28 doesn’t leave a lot of choice. Of course cars don’t come for free, but I am prepared to widen the scope and at least consider value elsewhere.

I think that a Picanto, i10 and Aygo cars are possibly too small. She had an Aygo for four years and it was very tight at time getting all her kit in it. Yes, the engine is unburstable and goes well but with her trips several times a year of 300+ miles a car with less drone and road noise together with more road presence especially on motorways appeals. Anyway, the plan is in place and with the helpful comments received hopefully we can take time and care without having to worry about a car crisis necessitating more immediate action.
