may be sharing my experience would help...
i also had the same 0.7M budget that u ve got, though i dint consider liana (resale issue) at all just becoz i thot that i would save some more money and increase my budget to 1M in a year to buy a civic 05.
anyways i ended up stretching my budget to 775k and got myself a exi 2002 but since that day i am spending all my savings to set this car as per my likes..
i have changed the whole suspension, new tyres, mounting and a few other maintenace works and now i just feel like bearing this car...
it's not that i was an idiot to buy this troubled car, we usually check body and engine while buying a car. with these old models you never know what's coming next till they are with for quite some time...
so my advise would definitely be a newer liana, just find one that is well maintained and nicely kept.
best of luck.
