2005 nissan maxima sl

Runs drives stops but needs work.
has an engine code p0021 for oil valve solenoids but I replaced both & it still won't go away.
the seal on the rear oil valve solenoid I replaced is leaking onto the exhaust so it smokes a lil when it gets hot & i dont feel like doing it again since i have no garage.
i've lost all ambition in the car so I bought another vehicle & don't want this car sitting for the winter rotting away.
its from the Carolinas never seen snow,the underneath looks amazing.
comes with 18x8 jnc black chrome 10 spoke rims on brand new tires not even 100 miles on the set & were bought over the summer brand new for $2600.
cold air intake $350,jdm computer chip $350,comes with brand new 1-3 inch adjustable coilovers $500,smoked taillights $350(also have the factory lights),double din cd player & all the wiring ran for Amp & sub $300,rain guards,tint,all l.
