Definitely go for the 1.5TC. Huge diff in power (40hp/54nm more). To me 153hp for a 1.5+ ton car is underpower.
Unless you drive slow all the time. Is alot fun to drive with the 1.5TC, more fuel efficient, new tech & cheaper road tax.
Spending almost 150k, get la something more powerful and more fun to drive SUV. lol. not the boring 150hp NA old engine...

Civic TC already in market almost 1 year, so far no issue with the turbo engine. And turbo engine is not new anymore. Audi/MB/BMW etc been using turbo for years and now japanese manufacturer starting to move to turbo also.

Don't worry too much on the long term reliability la. Japanese tech are quite reliable. unless u want to stuck with boring N/A or buy a basic car without tech if you worry
