Suzuki Swift Sport (2018 on)
1.4 Boosterjet Sport 5dr
Fantastic
This is genuinely the best car I have owned. It is significantly faster than the stats would suggest (especially in-gear), yet returns almost 50 mpg. Even around town, you can expect 40 mpg (so much better than the Polo GTi we also own - although I accept the Polo is quite a bit faster).
The interior space is very impressive for a small car; fitting 4 adults with relatively ease. I accept the boot is very small though, which does limit its practicality a little. The ride can be tad firm, although it's perfectly acceptable, especially when compared with our previous car, a Ford Fiesta ST3 (2017 registered).
Bad Points?
Infotainment system is a shocker - very slow to react and doesn't always read a USB, which can be a little annoying.
It has diamond cut alloy wheels, which are stupid (that's a general criticism of diamond cut wheels) and very prone to marks and corrosion. Ours started going after 1 year and 4,000 miles but Suzuki replaced them free of charge. the replacements have lasted no better (although my wife blames a curbed wheel as the reason - that was me, not her :)
Overall, this is a fantastic car.
