my .02 as i have both cars. i needed a mpg car and would rather eat a s*** sandwich than drive a kia or hyundai. was out the door @ 14500 for a 3i touring 5spd. this means its got the alloys, sat, cruise, fogs, mats, wheel locks, steering wheel controls, pw, pl. invoice was 15.5k
this included a paint/interior protection plan that covers anything that gets on the paint from sap to bird crap that messes it up and anything that might stain the seats for the life of the car. im gonna spend a lot of time in that car since its for road trips so i got the "scotchguard" thing cause im sure to spill something. oh and a couple of oil changes.
as of today with 900ish miles and 99% hwy miles im getting 33.4mpg now i wont touch the break in issue but to me its not broken in. with that said i figure if i see 33-35 out of it im golden. this is with no tint, avg about 75 and have the ac on med speed.
that day i was checking out the ms3's - found a gray ms3 for 23.5k (sticker) and they started the song and dance about last year for awhile, its an 08.5, its a newer color, etc. so i told them to eff it and id take my truck and go. an hour later i was out the door with my speed 3 and a years worth of oil changes for 21k with my 1k down. they gave me 1k more than payoff for my tundra and i took most of my mods, parted them out already for xtra cash for the ms3 and the 3i.
its a freakin buyers market. i drove the ms3 and they knew i liked it. when i told them i was just going to keep the truck its amazing the deals that came available. mazda na credit was competitive with rates but my credit union killed. paying 1.9% for both cars for 48 mos thru pentagon fed cu.
if your looking for some good mpg the 3 is a good car for it. good ride quality, styling, options to mod it, etc. if you want 45 mpg go get a 2dr accent, 50mpg wait 6 mos for a hybrid and hope to hell it doesnt break and your in a small town. you can ride home in the aaa truck cause no one there can work on your hybrid.
when i first joined this board i had an 02 protege. had great plans for it, covert it to a msp. moved and went for my post grad degree. car got left in the dust. that mazda had 120k on it when i let it go and i never had an issue. its the reason i went back to mazda and bought two of them. yeah the paint might be a little thin (clear bra/vinyl bra) or the radio might not be as clear as you want it but its a effn reliable car.
my .02
oh and insurance, about 15$ different a month from 3i to ms3. worth every penny and thats will full car replacement, oem parts, etc. multi car disc (duh) and being with the same company for 15 years and having a couple of claims for minor crap.
