How old is the Child? What is the weight of the child?
The "best"
infant seat is the one that will install properly in your car, will be used correctly everytime, and fits the child. Some have more "ease of use" features, or will last your child longer.
If I remember correctly the Mitsubishi Eclipses have a VERY steep recline on the seat bottoms. This causes seat installation issues for small babies because they really need that 45 degree recline. Once the child is old enough to hold the head up that 45degree isn't always needed. You can have the seat angled all the way up to 30 degrees (but no more).
I highy recommend the
Chicco keyfit 30, or the Grace
Safeseat. They both go to 30lbs, and typically are very easy to install. The Base on the
safeseat is raises quite a bit to ensure you get a 45 degree recline.
The best thing to do is to go to your local BRU store (or whatever), and try these seats out in your vehicle before purchasing. Many of the stores will allow you do this. Either an employee will follow you outside, or they may have you leave your driver's license at the counter.
