1.0l TSI SE suitable for private hire use ?

I'm currently looking at purchasing a car for work, taxi driver.

Only ever driven octavias 1.6 tdi and recently 1.5tsi act.

Test drove a 1.0 tsi se yesterday and was surprised how well it drove, was expecting it to be sluggish with a considerably smaller engine than I'm used to.

Will mainly be used short stop start journeys with an old dear and shopping in the boot with the occasional boot full of suitcases with 4 extra bodies going to the airport

Bit of gogogling suggests carbon build may be an issue that'd need monitoring, anything else i need to know to help make a decision ?
