My wonderful husband is wanting to buy me a new car. I have to choose either the Rx 350 or Rx 450 hybrid. I've driven both and see pros and cons for each. I'm planning on keeping this car at least 8 years. I currently drive a Toyota Highlander so the Rx350 felt very familiar. I'm not an aggressive driver so I have always hit the mark for fuel efficiency and I feel confident that would be the same for the Rx 350. However, the hybrid was equally comfortable. It felt heavier and was eerily quiet but the horsepower was amazing. There was nothing I didn't like other than it just felt different and I would have to get used to it. The difference is justifying the $6,000 in price. 90% of my driving is in town (work is only 6 miles away) so I know I can benefit on the fuel economy, Gas prices are only going to go up so that's a variable. Recouping my $6,000 is questionable over the long haul according to my calculations and what I've read on the Internet. So I'm torn. Should I stay with what is familiar and continue to grit my teeth every time I refuel or should I leap into new age technology and cross my fingers? I don't know what to do. Please share your thoughts. I told my husband I would make my decision within 24 hours.
