Nissan, Honda or Toyota for my 2nd car

I'm looking for a nice sized sedan for me and my 2year old. I would like a car with good gas mileage, good space, reliable and one that does not have history of serious issues and non-expensive to fix.

Why are they different than other engines?

Why do Honda engines, new and old, low miles to extremely high miles (over 190, xxx) love to rev without any problems? My car starts ticking when I try to rev it and my friends honda that has 200xxx miles on it revs like a champ

What is this thing I found in my honda st1300?

Found it Velcroed in to the rear right saddlebag not wired to anything. The larger box has "r/a" and "f/a" ports as well as "port 1" "spdomtr" and "remote". The port 1 was wired to another box with 3 DC electrical ports and on the other side, a rusty silver box and red and black (power?) wires coming out.

The smaller box says "Able 2 products company" and there's no text on the larger box or it is covered up by Velcro which I'd rather not remove if I don't have to. Any ideas?

Thanks in advance, best answer will be awarded!

The smaller box is just a power accessory box, I found it here. Still have no idea what the bigger box would be used for What is this thing I found in my honda st1300 - 1

Scooter smells of raw gas after shutdown?

Have checked for leaks, found none. Carb is not draining/overflowing. No fuel in exhaust. No drop in fuel consumption (over 80 mpg). Scooter runs fine, no hesitation, no loss of power. Have changed the oil and it is normal. 2005 Honda Vino 125. Started about a week ago.

Thoughts?

Added (1). 2005 Yamaha Vino, my bad. Plugs are ok, no fuel, tan color.

Added (2). I replaced the fuel cap, fuel lines, petcock, carb bowl gasket and air filter. I do not know which part fixed the problem but the smell is gone.

Best 4 seater (can be 2-door) sporty car for 5k?

Looking for some suggestions for a fun car with a hint of practicality. Currently I have a 1990 Honda Prelude Si. The handling is fantastic and the vision is the best I've driven in but it's not going to last me much longer. It has 4 seats, but the back two are only suitable for smaller friends. Looking to get a car with a litte more space, but nothing large. A convertible would be nice but is not required. I would take a 4-door, but would prefer a 2-door w/ 4 seats. Some of the ones I've been looking at are the Toyota Celica, Acura Integra, Mitsubishi Eclipse, etc. Been looking at some older 2-door Mustang convertibles and more options such as that would be great.
