Suzuki Swace

The Suzuki Swace is a pragmatic estate that swaps showy design for roomy practicality and a quiet, comfortable ride that suits everyday family life. It won't thrill the enthusiast, but its sensible charm, dependable build and clever packaging make it a smart pick for buyers who want fuss-free usability rather than headline-grabbing performance.

I have the Swace — it drives much more frugally than you state: 1:23. A downside as you get older is that getting in, and especially getting out, becomes harder because of the low seating position. The advantage of the low seat is better fuel economy. 16‑inch wheels are also likely to be more economical than larger ones. Rear legroom is poor. It would be nice if the rear bench were on rails like the Renault Twingo. Shrinking the boot would give more rear legroom. The 2014 Toyota Prius was the last to offer lots of rear legroom — after that it’s been rubbish.
