Finding some rare car in Export car mission GTA Sanandreas Hints

I really enjoy this mission so I give this to you.
Some cars will appear many before the exportin mission but after startin the mision they are
almost impossible to find.
I recommend to save before the mission start, then watch the list of cars. Load save, store
some rare cars that you can't find them easily (such as Sentinel, Stafford, Journey ect.)
then do the mission
I will guide sone way to find those rare car:
* Sentinel:
A foor doors car which can be found at the the tv studio (not far from the "Vinewood" Sign).
This place is just like the film studio in GTA Vice City and it could be easier to find it if
flying with Jetpack.
* Journey:
A white RV. Sometime park at bar in the country side but when the export mission starts you
have to look it up in the country road.
Other way not to go to the country is using the code "FVTMNBZ".
* BF Injection:
Can be found in the moutain country or at the westcoast of San Fierro.
Another way is using the code "CRAZYTOWN". It will apear a lot. (better not using this way
cauze you will becom freaky ugly clown).
* Euros:
Go to the The Camels Toe casino (pyramid with
a sphinx in the front) in Las Venturas. The Euros is under the sphinx.
* Cheetah, Comet, FCR - 900, Buffalo, Slamvan:
Easy to find in Las Venturas at night.
* Stafford:
Appear alot in the Northest area of Las Venturas
