^ Second to this. Yes, there is nothing wrong with the GDI system. It does cause a little more build up on the valves and such, but as long as you follow the maintenance schedule, it can be just fine. Its just something to consider if youre being very frugal, the GDI's cost a little more to maintain then the "standard injection" engines. Pennies over the life of the car really. It only becomes an issue if you dont maintain the system.
As for the honda's blowing wrist pins.. Well. Heh.. Some certain micras were known to have a knock in the motor. Some. Just like 2.7 chryslers blowing motors, ford focuses eating trannies, 1.8 VW's blowing water pumps etc...
What im getting at is, any manufacturer can have a glitch. It's happened to us. Its happened to almost every manufacturer known. The big thing is making sure your warranty covers any headaches. Just about all of them are good up to 100,000km. Some are even further.
Further to what Micropolis is saying, you can get an SR if you like the extra bits. Its a matter of what you want for the money. When you test drive it... does it talk to you? For example, my wifes VW jetta. Gorgeous car. Heated seats, back up cam, phone hookup, you name it. The drive tho? Souless. It has zero personality.
I like the micra for its handling and its price point. Its cheap and is a really fun little car in the corners. Its not a fast car, but its cheap thrills for me. The micra is a zippy little thing. Like a young kid. It wants to play. You poke the gas, it gives you a response. Turn her into the corner and it leans a little and goes like hot snot.
