Thanks SDate42
I need 4600mm to carry long stuff on the roof, legally, about 6.5m long.legally 1200mm max out the front (Front Ladder rack to hold it up, not heavy), plus the wagon plus the sum of 60% of wheel base from back wheel outback. 1200+4600+1600 (1600 makes up about 800 from back wheel centre to back of car plus about 800 outback) = 6600mm. 100mm is for not having the stuff perfectly positioned on the racks officer. Its close.
Lancer wagon and Astra wagon (Though Astra might be too short at 4.515mm long) are wagons with a very flat roof line like the old day wagons, with no stupid sloping back roofs. So the roof racks, I can have 1 rack up front over the drivers head and way down the back just in front of the tail gate. Most wagons these days only allow for the front rack behind the drivers head on the roof and over the heads of the rear passengers, which is pretty useless (about 600mm separation), unless you only want to car a boggie board
.
Also as a highway car whats the 2.4 litre manual like on fuel L/100 ks?
next option is going real old to a magna wagon which I don't want to go that old. Not really. Too thirsty in the city.
