i looked at all the 3 cars you mentioned last month.
1. 4大1小(4歳),間中6-7人 - So sliding door is better - Freed or M5
2. 性價比高 (性價比 must be M5), simply look at the price
3. if you want better fuel economy and more morden interior look choose Freed
4. if you want more space inside, choose M5
5. stepwgn or serena are more expeisnve, but not much, but the car is bigger in size for parking and less nimble handling like these smaller 7 seater, if I 4大1小, i will choose serena. I currently 2大1小, 間中 5人 and very very間中6-7人, so i picked M5.
you may also consder 2nd hand Serena if you budget is limited. you should be able get nice one around 250k
WISH is a good chocie if you can accept no sliding door.
"但我自己覺得坐上去中排,雙腳好似屈膝比其他兩款多" no comment, but i think is good enough, at least as good as the space in the back of a benz E-class
if you go to Mazda show room, actually next to the M5, there is a table showing comparsion between Freed M5 WISH. take a look and you will understand why M5 is 性價比高.
but of coz it won't show what other brand is better.
WISH is Toyota and Toyota is loved by all Hong Kong Japanese car lover and should hold value better and MAZDA is a brand that many pepole will say 'rubbish brand'.
FREED has keyless entry with start button whereas Mazda doesn't.
FREED use less fuel but maybe a bit slower and cheaper annual liscence fee
I am not sure but i think FREED also include reverse cam and touch screen hi fi system where as WISH and M5 only come with reverse parking sensor and old school hi fi
the decision is easy, do you want Sliding door, if not WISH, if yes which one you like the look more......honda or mazda.
